THOMAS H. SEELY, OF BOSTON, MASSACHUSETTS, ASSIG-NOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom. it may concern:

Be it known that I, Tnoaras H. SEELY, a citizen of the United States, residing at Dorchester, Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Packages of W'elting; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as w ll enable others skilled in the art to whlch 1t appertains to make and use the same.

The present invent-ion relates to a package of welting, and more particularly to a package of welting which can be readily permeated by Water to temper the welting.

The welt-ing is usually supphed to-the shoe manufacturer in compact tightly-coiled rolls. In order to prepare the weltingfor sewlng it to the lasted shoe, it is usually run through a grooving and beveling machlne which cuts a stitch-receiving groove 1n the face of the welt and bevels the edge of the welt. It is desirable, particularly where any quantity of prepared welt-ing is kept n stock. that the prepared welting be kept 1n comp act packages which are convement to handle. After the prepared welting 1s delivered to the operator of the welt sewing machine, and before it is sewn to the shoe, the waiting is soaked in water to soften or temper the leather so that the welt is more easily applied and sewn to, the shoe. orderthat the welting may be conveniently tempered by the operator before he, uses t on the welt sewing machine, the package in which v the ,welt is suppliedto him should be capable of being readily permeated by water to temper the welting.

The object of the present invention 1s to provide a package of welting whlch can be conveniently handled and which can be readily permeated by water to temper the welting preparatory to sewing it to the shoe.

lVith the above object in view, the present invention consists of the package of welting hereinafter described and particularly point ed out in the claims. 1

- In the drawings which illustrate the preferred embodiment of the present invention,- Figure 1 is a perspective view of the package of welting; and Fig. 2 is a side elevation.

.Referring to the drawings, the package of melting is a coil of a generally cylindrical outline and of a greater length, taken along PACKAGE OF WELTING.

Serial No. 750,308.

the circumference of the coil; In making this coil, after one spiral has'been wound, the welt is deflected toward the opposite end of the coil and is wound five-eighths of the distance around the circumference of the coil to form a second spiral. These two spirals taken together extend one and one -v quarter turns around the coil so that the third spiral begins one-quarter of the circumference of the coil in advance of the beginning of the first spiral. The winding is continued and the welt is deflected back and forth until eight spirals have been wound, the welting in these eight spirals forming live complete turns around the coil. The

ninth spiral will be wound directly over the.

first spiral, the tenth spiral will be Wound directly over the second spiral, and so on.

The coil illustrated in the drawings will therefore consist of eight sets of spirals, each set of which consists of the superposed parallel spiral layers or laminae of welting which are laid fiat one on top of the other in the process of winding. Four of these eight sets extend in the same direction longitudinally of the coil and are spaced apart from each other one-quarter of the distance around the coil. The other four sets extend in the opposite direction longitudinally of the coil, are spaced apart from each other one-quarter of the circumference of the coil and intersect or criss-cross the first four sets. In the side elevation of the coil, shown in Fig. 2, the outside spirals of five of these eight sets are visible. The outside spirals 5, '7 and 9 form the top layers of three of the sets which extend in the same direction, the fourth set being at the back side of the coil and therefore not visible. The spirals 6 and 8 are the top layers of two of the other foursets, the other two sets of this four being on the back side of the coil and therefore not visible. These five outside spirals 5, 6, 7, 8

and 9 intersect or criss-cross each other at the points 10, 11, 12, 13 and l t. Beneath these outside spirals are the inner spirals forming the inner layers or laminae of the sets.

As shown in Fig. 2, the set of which 7 is the outer spiral consists of a plurality of inner spiral layers or laminae 20, 21, 22, and so on radially into the coil. The spirals which extend in the same direction and which are adjacent are, as above pointed out, spaced apart a quarter of the circumference of the coil so that spaces or interstices are left between the edges of the welt. As shown inFig. 2, the space between the edges of two adjacent spirals is greater than the width'of the welt strip. Since the welting is coiled in a plurality of sets of superposed layers or laminae, the spaces or interstices between the edges of the spirals which form these layers or laminae coincide to form holes, such as 25'and 26, which extend substantially radially into the coil between said layered sets of spirals. At the points of intersection of the spirals, the layers or laminae of each set are alternately interposed so that between such points of inter-- section, the layers or laminae are separated from each other to leave spaces or interstices between the opposing fiat faces of the welting of the superposed layers. Such interstices are shown, for example, at 30 and 31 in Fig. 1 and at32 and'33 in Fig. 2 of the drawings. The interstices between the welt layers, such as 7, 20, 21 and 22 separate these layers between points of intersection 11 and 12 and form connecting interstices between the holes 25 and 26. Between the points of intersection, the welting is, therefore, exposed on all sides, so that it can readily absorb moisture. The entire package or coil is honey-combed with spaces or interstices between the edges and the faces of the welting and when this open-work package or coil is dropped into water it is readily permeated by it. The package is tied together by two strings 35 and 36 which prevent the welting from uncoiling and keep it in convenient condition for handling.

The welt strip is sufliciently broad so that it cannot be easily bent laterally. If it is attempted to bend the welt strip sharply laterally, the stiffness of the strip will resist such lateral bending. Moreover, if the welt is given a comparatively sharp lateral bend it will cause one edge to be curled or buckled. The welt strip, however, can be readily bent in the direction of its thickness. Consequently, as is clearly shown in the drawings, the welt strip at the ends of the coil where the strip is deflected is not bent sharply laterally of the strip but lies in a surface which is inclined to the axis of the coil. This surface is a ruled surface, the generating line of which moves about and is inclined to the axis of the coil and the surface is inclined in such a direction that it intersects the axis of the coil beyond the end of the coil. By virtue of the slight twisting of the welt strip so that its edge nearest the end of the coil is nearer the axis of the coil than the other edge of thestrip, the surface in which the welt strip lies is changed from the cylindrical surface in which it lies at the middle of the coil into a surface which is inclined to the axis of the coil, and which is in conformation something like a part of a cone. The effect of so inclining the welt strip at the end of the strip, is to cause its deflection longitudinally by bending it in the direction of its thickness instead of in the direction of its width.

The package or coil of welting of the present invention is compact enough so that it is easily handled and stored, but at the same time it can be readily permeated by water to temper the welting. The operator of the welt sewingmachine can drop the package as it is delivered to him, directly into the water to temper the leather. The package of soaked or tempered welting is in a convenient form to handle and use on the welt sewing machine when it is taken out of the water. The open-work package or coil is so readily permeable by water that the operator of the welt sewing machine need not unwind the welt, but simply has to drop the open-work package or coil into the water and let it stay there until he needs more welting for his machine. I

\Vhile the preferred embodiment of the present invention has been specifically illus- V trated and described, the present invention is not limited to its preferred embodiment, but may be embodied in other packages or coils of welting within thescope of the invention as set forth in the following claims 1. As an article of manufacture, a package or coil of welting of a generally cylindrical outline and of greater length than the width of the welt strip, consisting of a continuous strip of welting in a flat or untwisted condition arranged in criss-crossed or intersecting spirals extending back and forth' longitudinaly of the coil and separated from each other to form an open-work package or coil of welting which can be readily permeated by water to temper the welting preparatory to sewing it to a shoe.

2. As an article of manufacture, a package or coil of welting of a generally cylindrical outline and of greater length than the width of the welt strip, consisting of a continuous strip of welting in a flat or untwisted condition arranged in criss-crossed or intersecting spirals extending back and forth longitudinally of the coil, said spirals being arranged in a plurality of sets of supoi-posed parallel spiral layers or laminae of welting laid flat one on top of the other and spaced apart to leave holes extending substantially radially into the coil between said sets, the layers or laminae of two such sets being alternately interposed at the points of intersection of the spirals and the layers or laminae of each set being separated from each other between such points of intersection to leave the welt strip exposed on all sides, so that the package or coil of welting can be readily permeated by water to temper the welting preparatory to sewing it to a shoe.
